Doing the windows on one of my regulars last week, a neighbour a few doors down pops out and says 'ah brilliant, a window cleaner, I'm usually at work so I don't get to see one. Any chance you could clean mine?'
'Yes, of course' I say, 'a one off or a regular 4 weekly'
'I think regular'
So, I priced for what I would charge her a month, and no extra for a minging first clean, thinking I'll take the hit for a regular,
'All finished' I say, she gives me the £12 quoted, I get my book out to get all the details down and she turns around and says
'Actually, I'll leave the monthly and just catch you when I can'!!
Needless to say, I stewed on it all day. Lesson learned.
